基于多元线性回归方法的砌体结构加固费用估算模型研究
A Retrofit Cost Estimation Model of Masonry Structures Based on the Multiple Linear Regression Method
摘要
Abstract
In this paper,retrofit costs and relative building parameters of masonry structures in Shaanxi, Shanxi,and Sichuan Provinces were collected,to enable a retrofit cost estimation model for masonry structure buildings to be developed.A regression and validation database,including the retrofit cost estimation models of 35 buildings,was built,and the building parameters which influence retrofit costs analyzed.Then,based on the multiple linear regression method,four models were established using the existing retrofit data with SPSS analysis software.After evaluating the four models according to their corresponding evaluation criteria,an optimal rapid estimation model for the retrofit cost of masonry structures was proposed and verified.The results show that the re-gression model meets the precision requirements and could be valuable in practical engineering.关键词
